Application le'd October 30, 1914. Serial No. 869,479. 4

To all whom, it may concern:

Be it known that I, WINTHROP PARKER, a citizen of the United States,residing at Manchester, county of Hillsboro, and State of New Hampshire,have invented an Improvement in Spinning and Twisting Machines, of whichthe' following description, in connection with the accompanying drawing,is a specification, like characters on the drawing representing likeparts.

This Vinvention relates to spinning and twisting machines of that typewhich are constructed to lay on the yarn receiver irst a preliminarywinding and then a main or service winding, and the principal object ofthe invention is to provide a machine of this type with means foractuating the ring rail to lay the preliminary winding which is separateand independent from the usual builder motion by which the main orservice winding is laid, and which is provided with means forautomatically rendering the preliminary winding mechanism inoperativeafter the preliminary winding has been laid whereby the regularbuildermotion will come `into play automatically after the -preliminarywinding has been laid to lay the main or service winding on the yarnreceiver. A l

Further objects of the invention are to provide a machine of the abovetype with means for laying the preliminary winding on the yarn receiverwhich are capable of adjustment so as to provide for varying the size ofthe preliminarywinding and its position on the bobbin or yarn receiver,and otherwise to improve spinning or twisting machines of the abovetype, all as will be more fully hereinafter described. s

In order to give an understanding of thef invention I have illustratedherein some selected embodiments thereof which will now be described,after which the novel features of the invention will be pointed out inthe appended claims. I,

In the drawings, Figure 1 is a partial view of a spinning' and twistingmachine showing my improvements applied thereto; Fig. 2 is a detail planview of the mechanism shown in Fig. 1 for disengaging the preliminarywinding mechanism at the completion of the preliminary winding; Fig. 3is a side elevation of a different form of disengaging means; Fig. 4 isa section on the line Fig. 2; Fig. 5 is a section on the line fy-g/,Fig. 2. Fig. 6 is a view of the Vbobbin showing the preliminary windingthereon.

The portion of the spinning or twisting frame herein shown comprises thehead or end frame l, the spindle rail or frame 2 in vwhich the spindlesor other yarn receivers 3 are rotatively mounted, and the ring rail 4carryingthe spinning rings. This ring rail 4 is capable of a verticaltraversing movement to lay the yarn on the yarn receivers as usual, andthe device herein illustrated lincludes the ordinary builder motion forgiving a traversing movement to the ring ring rail 4 through lifterrods. This rocker is shown at 5, it being pivoted to the frame at 6 andit has engagement with the lifter rod 7 secured to the ring rail 4. Therocker 5 is connected to the usual builder chain 8 which leads to thebuilder arm 9. This builder arm is given a constant stroke' through arotatable cam member 10, as usual, thereby to cause the ring rail 4 tohave its traversing movement. As the builder arm rotates, the builderchain 8 is gradually let 01T or lengthened through the operation of thepick-pawl 11 and pick-wheel 12, thereby to give to the ring rail therequired gain as the yarn is laid on the yarn receiver. Inasmuch as theparts above described are -such are are commonly found in spinning ortwisting machines, Indo not deem it necessary to further describe them.

In wmdingyarn on a yarn receiver, it is `often desirable to lay on theyarn receiver irst a preliminary winding, and then a main or servicewinding. This preliminary winding is sometimes used as a so-called bunchto coperate with the feeler of a lling-replenishing loom for the purposeof causing filling replenishment upon substantial eX- haustion of thelilling, and it is sometimes used merely to provide a suilicient lengthof yarn to constitute one or two picks so that lilling replenishmentwill take place before 'fao illustrated embodiment of the invention Ihave chosen to actuate it from the gearing in the head or end 1 of theframe, preferably from the front top roll. This independent mechanism,which I will hereinafter refer to as the preliminary winding' mechanismis herein illustrated as comprising a reciprocatory actuator 13 operatedthrough an instrumentality independent 7from that which actuates thebuilder motion and adapted to be connected to or disconnected from thering rail 4 independently of the regular builder motion.A I find itconvenient to effect the connection of the actuator 13 with the ringrail 4 through the rocker member 5, although this particularconstruction is not essential to the invention. I also ind it convenientto give the` actuator 13 its reciprocatory movement from the front toproll, this being the construction herein shown." The actuator 13 is inthe form of a bar which is connected at one end t'o a crank pin 14carried by a crank member 15 that is rotatably mounted in suitablebearings inthe frame. The eccentricity of vthe pin 14 relative to theaxis of thecrank 4member 15 serves to determine the length of traverseof the preliminary winding mechanism. This member 15 is driven from thegearlng constituting the head of the machine, preferably from the fronttop roll, and for this purpose said member 15 is in the form of a bevelgear which meshes with a bevel gear 16 carried on a shaft 17 that inturn is driven from the shaft 18 of the front top roll throughintermeshing gears 19. This particular form of gearing is, however, onlyillustrative of one method of giving reciprocatory movement to theactuator 13.

The actuator 13 is thus a constantly-moving actuator having a constantreciprocatory movement. As stated above, I nd it convenient to providefor the connection of the actuator 13 with the ring rail 4 through therocker member 5, and for this purpose I have shown the rocker member asprovided with the finger or arm 20 which is adapted to engage in arecess or notch 21 formed in the actuator. y When the finger 20 is thusengaged in the recess 21, then reciprocatory movement of the actuator 13will rock the rocker 5 thereby raising and lowering they ringA rail 4.This traversing movement of the ring rail 4 which is effected by theactuator- 13 is 'the movement which lays on each yarn receiver 3 itspreliminary winding. The movement which is given to the ring rail 4 bythe actuator 13 is not interfered with by the operation of the ordinarybuilder motion, for thevibratory movement of the builder arm 9 willsimply place more or less slack in the chain 8.

While the actuator 13 may be given a re ciprocatory movement atanydesired speed, I will preferablyso operate said actuator as to give thering rail 4 a comparatively rapid traverse so that the preliminarywinding which is shown at 22 in Fig. 6 will be laidv with aicoarsepitch. The advantage of this is that the bobbin can be more readilystripped of the renmant of yarn left thereon after it is discharged froma filling-replenishing loom than if said remnant of yarn were laid withthe coils thereof tightly together, and any desired size of bunch can bemade with less yarn, thereby reducing the amount of waste yarn left onthe bobbin after it is discharged from a illing-replenishing loom.

My invention also comprehends means for automatically disengaging theactuator 13 from operative connection with the ring rail when thepreliminary winding is completed so that vthereafter kthe builder motionwill come into play automatically to lay on the Varn receiver the mainor service winding. This automatic disconnection of the actuator 13 fromthe ring rail is herein provided for by a disconnecting device which isadapted to raise the actuator at the proper time so as to disconnect itfrom the finger 20. This disconnecting member is herein shown in the'form of a cam or arm 23 which'is mounted on a shaft or stud 24 that isjournaled in suitable bearings 25 carried by a bracket or support 26secured to the Vframe of the machine. This disconnecting member 23 isnormally inoperative, but is actuated to bring it into .position toengage the actuator 13 and raise the notch 21 of the latter out ofengagement with the finger 20 at the time that the preliminary windingis completed. For this purpose I have herein shown a ratchet wheel 27which is fast on the shaft 24 and therefore rigid with the disconnectingmember 23 and a pick-pawl 28 which is carried by the actuator 13 and isadapted to intermittently advance the ratchet 27 as the actuatorvibrates. During the reciprocatory movement of the vibrating actuator 13vthe ratchetwheel will be intermittently turned in the direction of thearrow in Fig. 1, and the disengaging member 23 will thus be carriedaround 23 f rotates `it" en,Qjages`I the 'lower endfof the:

provided with a plurality of apertures 49 into anyone of which the stop42may be set, and thus the amount it is necessary to rotate 23 from itsinitial position into engagement with the member 29. lcan be adjustedand varied.y This provides for laying a greater `or less amount of yarnin the preliminary member 50 is mounted on a shaft 5 1 journaled in abracket 52, which shaft has therey before the on a gear 53 that mesheswith and is driven bv a pinion 54 rigid with the ratchet wheel 27 withwhich the pick-pawl 28 engages. using gears 53, 54 of proper sizes, itis possible to provide a construction whereby the ratchet 27 may makeseveral revolutions brought into operative position.

In the embodiment illustrated in Fig. 3 the disengaging member 50 isreturned to its normal initial position by means of a spring 58 similarto the spring 40 in Fig. 2, one end of the sprlng being connected to thebearing of the shaft 50 and the other to the gear 53;

The gear 53 is tion 5.6 which engages a stop member 57 carprovided witha stop projecried lby the bracket 52, said stop projections limiting thereturn movement of the member 50. Fig. 3 shows the parts in position foroperation. As the actuator `13 vibrates the ratchet 27 is rotated in thedirection of the arrow thereon, and .through the gears 54, 53

the disengaging member 50 is rotated in the' direction of the arrow.When the member has made a successive complete rotation 1t engages-thelinger 59 extending from thev actuator 13 and lifts said actuator out ofengagementfwith the rocker member 5, yand during this movement the pawlk28 is disengaged from the ratchet 27 by the parts 33, 35. In otherrespects the device shown in Fig. 3 is similar to that shown in Figs. 1and 2.
